Though we had that discussion recently, I will again point out that, from how I see it, the term "SSR" does not include/refer to classic server-side applications like PHP, Django, ASP, whatever. Instead, it is used specifically to refer to single-page applications, rendered on the server. Nothing else. If you search for SSR, you will not find PHP, Django, ASP.
